As a result, Caesar ignores her plea and goes to the senate house.Portia is more assertive than Calpurnia.Portia is strong-willed, dignified and asserts her right to know her husband's innermost secrets. She is a brave woman. She says that she is not an ordinary woman as she is Cato's daughter and Brutus' wife. And hence, she says, she can keep secrets. But in the end she commits suicide as she is not able to bear her husband's grief. Her bravery, dignity, determination and assertive nature makes her totally different from Calpurnia.
